We look at the division of 640719 by 69 
We want to divide 640719 by 69.

Moving on to step 1:
When dividing 6 by 69, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 69

Moving on to step 2:
64 divided by 69 is 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Bring next digit (0) of the dividend behind the 64 and repeat the process: 640 / 69

Moving on to step 3:
69 goes into 640 9 times with a remainder of 19.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 621 from 640 to get 19.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 69

On to step 4:
197 divided by 69 is 2 with a remainder of 59.
Use 2 as the next digit of our solution. 
Result so far: 92.0
If we subtract 138 from 197, we get 59.
Fetch the next digit (1) from the dividend, attach it to 59 and continue: 591 / 69

Moving on to step 5:
591 divided by 69 is 8 with a remainder of 39.
The next digit of our result is 8. 
Result so far: 928.0
If we take 552 away from 591, we end up with 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 69

On to step 6:
69 goes into 399 5 times with a remainder of 54.
Use 5 as the next digit of our solution. 
Result so far: 9285.0
Subtracting 345 from 399 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 7:
The number 69 fits into 540 7 times, leaving a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 9285.7
Deduct 483 from 540 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 8:
570 divided by 69 is 8 with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 9285.78
Subtract 552 from 570 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
180 divided by 69 is 2 with a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 9285.782
The remainder is 42 after subtracting 138 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
The number 69 fits into 420 6 times, leaving a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 9285.7826
If we subtract 414 from 420, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
The number 69 fits into 60 0 times, leaving a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 9285.7826
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 12:
The number 69 fits into 600 8 times, leaving a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 9285.782608
If we subtract 552 from 600, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
When dividing 480 by 69, we get 6 with a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 9285.7826086
The remainder is 66 after subtracting 414 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 14:
69 can be fit into 660 9 times, resulting in a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 9285.78260869
Subtracting 621 from 660 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final outcome is 9285.78260869, with a leftover of 3.9e-08.
